- create a helper class to set up Disassembler for testing
- add a helper macro to only compare disassembled instruction (ignore
the hex bytes), this is useful for comparing SSE instructions, whose
opcodes are defined in sse-instr.h, and use uppercase letters, but the
disassembly always uses lowercase
- emit and compare SSE instructions using macro list
